Facebook will expand its platform for mobile users but won’t introduce its own phone. 

CEO Mark Zuckerberg announced the company will make its “Facebook Places” app available on Google Android-based smartphones.  The Places app reveals a user’s location.  The example given was of a local merchant offering an impromptu discount to someone nearby who checks in from their cellphone via Facebook.  Facebook wants to make its social network of half-a-billion members available to people when they’re away from their computers.
